Letters Patent No. 93,886, dated August 17, 1869.

IMPROVEMENT IN WASH-BOILERS,

The Schedule referred to in these Letters Patent; and making part of the same.

accompanying drawings, and to the letters of reference marked thereon.

This invention relates to boilers and vessels in ordinary use for drenching and Washing clothes' and like materials; and

The nature of this inventionis in the arrangement and conformation of the diaphragm under which the heated fluid gathers, and which serves also as a support to the mateiials being washed, and as a guide to the descending currents otfluid. A

Said nature is also inthe arrangement of the rising tubes for carrying up the ascending hot column of fluid, and in their construction for distributing and dispersing the discharging volume from said tubes.

'lo enable those herein skilled, to i make and use my said improvements, I Will now more fully describe the same, referring to the accompanying Figure 1 as a sectional elevation longitudinally; to

Figure 2 as a transverse section; to

Figure 3 as a plan; and

Figure 4 as a sectional View of the discharging-nozzie, hereinafter' more fully described. y

I construct the boiler A of any usual material and forni.

Within said boiler, and resting upon the bottom thereof, I place the diaphragm B, of arounding form, as indicated in fig. 2.

Betwscnsaid diaphragm and the bottom ofthe boiler, there is thus formed achamber, B', which,A by its close proximity to the heated bottom, to which the heatsource is usually' contiguous, is intensely heated, and there is thus created a tendency of upward dow from said chamber B' ofthe fluid therein.

To allow the heated fluid, which is'usually water, to rise, I arrange the tubes C, theirinllux-openings being close to the' bottom of the boiler, and being turned toward the middle ot" the saine, as indicated in lig. 1.

Said tubes C are properly supported upon the bot.- toni and sides of the boiler, and rise up to the discharging-heads D,`i`rom which the fluid is dispersed over the clothes usually placed within the boiler A.

The expansion of the fluid in the lower part of the boiler, and especially in the vchamber B', thus creates a ilonoi theiluid to the tubes aforesaid, and an `ascension in the same.

In order that Vthe less heated fluid, in its descent shall` not check or reduce the force of the rising currents, it it advisable to localize each of said currents.

ASaid plates prevent the The colder tluid passes down near the side siu'face, of the vessel A, and to enable the same readily to enter under the diaphragm B, this is arranged with perforations b, and the wire or other guardfrarne,.b, the latter preventing clothes from choking orcovering the peri'orations b.

Again, to prevent the colder current from contact and check upon the ascending flow, the influx-orifices of the tubes C were turned, and run toward the middle of the boiler, as above indicated.

But, lastly, to prevent the descending flow to interfere with the rising one, and especially to prevent .the rising flow in the tubes C from being chilled bythe descending fluid, I arrange theside-plates E immediatelyin the rear ofthe tubes C, and secured to the sides of the boiler A.

along the tubes C, and at the same time form cham bers E', these being open at' the bottom, and lreceiving steam and highly-heated fluid from the lower parts of the boiler, and forming in this wise an additional heating-chamber acting upon the tubes C and the fluid therein.

The discharging-heads I) are formed of a central part, D, and the spouts D2. zSaid spoutsvare bent in any required form, and in order that the out-flowing water may be directed to any required point, I arrange the same adjustably as follows:

The spouts I)2 iit about the pipes d, and maybe turned about the same by thel handle d'.

In order to prevent disconnection, a groove, di, is formed in the pipes d, and a prong of the handle d1 engages therein.

For further distributing the outllowing fluid column, I arrange the discharge-orifice ein the central head D1, and the orifices c in the spouts D?, there being suoli a number thereof as may be deemed expedient.

Having thus fully described my said invention,

'What I claim, is-

'1. The arrangement of the vessel A, having arounded diaphragm, B, with perforations l) therein, and raised guards b' thereon, and combined with the tubes C, substantially as set forth.

l 2.' The side-plates E, arranged to form the heating chambers E', and combined with the tubes C, substantially as and for the purpose set forth.

Iii-testimony of which, I have hereunto set my hand, in the presence of witnesses.
